my problem is about maximum memory size stata can handle.
I tried to run the Nested logit command using stata.
my dataset consist of 15000 people and each with 77
choices. the dataset is about 200m. When I try to
run the program nlogit, it says that there is no room to add more variables
due to width
You have the following alternatives:
1. Store existing variables more efficiently;
see help compress.
2. Drop some variables or observations; see help
drop. (Think of Stata's data area as the area of a
rectangle; Stata can trade off width and length.)
3. Increase the amount of memory allocated to
the data area using the set memory command; see help
I compressed all the variable and set memory to 600m
which is the maximum that my OS would allow, it still
What is the limit number of obs stata can handle?
I wonder if there is other ways of increasing memory
to make the program run.
